Now I understand about snapshot.
I am asking for to taking backup(before upgrade) and restore(after upgrade). I will use CPUSE upgrade.

After upgrading our cluster, the old configurations, policy, and routing that will not be included in new version.
So, I want to restore our policy, routing and all configurations to our new version.
I want to know about complete backup method that able to restore at new version.
I really appreciate your suggestion. I am a newbie for checkpoint. Please kindly support me and kindly patient me.
